JOHN DRETSOH, OF CLARK COUNTY, SOUTH DAKOTA.

TRUCK FOR HARVESTING-MACHINES.

To all whom it may concern:

Beit known that I, J OHN DRETSOH, a citizen of the United States, residing in Clark county, State of South Dakota, have invented certain new and useful Improvements in Trucks for Harvesting-Machines, of which the following is a specification.

My invention relates to trucks for supporting the front of the platform of a harvesting machine and the rear end of the draft tongue and has for its object the provision of a truck pivotally secured to the draft tongue and aving an upright postsecured thereto with a s ring connecting said post and the tongue am a spring lengthened rod connecting the post and the tilting lever of the machine so as to counteract the jar incident to the truck striking stones, clods and other unevennesses in the field.

My improved truck will be described in detail hereinafter and illustrated in the accompanying drawings in which Figure 1 is a side view of a fragment of a harvesting machine showing my improved truck secured thereto, Fig. 2, a plan view of the machine fragment and truck, Fig. 3, a cross section of the truck, and Fig. 4, a longitudinal sectional view of the spring rod connecting the truck and tilting lever on the machine.

In the drawings similar reference characters indicate corresponding parts in all of the views.

A indicates the platform of a harvesting machine and B the tilting lever suitably fulcrumed thereon. C indicates the draft pole or tongue.

Draft pole C has rods 1 secured thereto, and extending rearwardly thereform, between which are pivotally secured the front end of platform 2 of the truck, the rear end of the truck being pivotally secured to the front end of platform A as shown at 3.

4 indicates the truck wheel journaled in an inverted U-shaped support 5 swivelly mounted on plate 6 secured to the underside of platform 2.

7 indicates a post secured to platform 2, S a spring connecting the upper end of post 7 an the rear end of tongue (I while 9 indicates a rod connecting the post 7 and tilting lever B.

Rod 9 consists of two parts, one part having a tubular portion 10 secured thereto and provided with oppositely disposed longitudinal slots 11 while the other part consists of a Specification of Letters Patent.

bar 12 slidably mounted in tubular portion 10 and having a pin 13 secured through it and the slots 11. 14 indicates a pin secured through tubular portion 10 and 15 a spring mounted 011 tubular portion 10 and engaging the pins 13 and 14. By this construction of rod 9 it will be understood that the spring 15 holds the rod in its fully extended position, normally, but should the wheel 4 encounter a stone 01' other obstruction so that the front of the truck is thrown upwardly the spring 15 will take up the jar incident thereto allowing the rod 9 to momentarily shorten so that the lever B and the machine does not feel the jar. Spring 8 also assists spring 15 on rod 9 in disposing of the jars of the truck.

The draft appliances consist of an angular frame 16 having one side 17 formed with a hook 18 at its rear end that engages eye-loop 19 on the end of bar 20 secured to platform A and the other side 21 having its free end formed with angular portion 22 that engages a hole 23 in the front of platform 2. 24 indicates a loop formed at the juncture of sides 1.7 and 21 of frame 16 to which is secured the draft evener 25. By this construction of draft appliance the evener 25 is brought as near to the platform A as it would be if the draft pole C had been secured to the )latform, so that the power necessary to pul the machine is less than in machines employing other forms of trucks in which the evener is secured to the draft pole in advance of the truck. This construction aided by the truck wheel 4 which is flanged as shown so that it cuts into the soil practically eliminates side draft.

Having thus described my invention what I claim 'is 1. In combination with a harvesting machine platform, a tilting lever fulcrumed thereon, and a draft pole, a truck interposed between said draft pole and platform, a post secured to the truck, a spring connecting the post and draft pole, and a spring extended rod connecting the post and tilting lever.

2. In combination with a harvesting ma chine platform, a tilting lever fulcrumed thereon, and a draft ole, a truck interposed between said draft po e and platform and pivotally secured thereto, a post secured to the truck, a spring connecting the post and draft pole, a spring extended rod connecting the post and tilting lever, and a wheel swivelly mounted on said truck.

3. In combination with a harvesting machine platform, a bar secured to said plat- 1 consisting of an angular frame, one side of the frame having a hook to engage the eyeloop aforesaid, the otherside of the frame engaging the front end of the truck, a loop at the juncture of the tWo sides, and a draft evener secured to the loo 4. In combination with a harvesting ma chine platform, a tilting lever fulcrumed T thereon, a bar secured to said platform havin an eyeloop in its front end, and a draft po e, a truck interposed between the draft pole and platform and pivotally secured thereto,-a post secured to the truck, a spring .lever, and a draft appliance consisting of an angular frame, one side of the frame having a hook to engage the eyeloop aforesaid, the other side of the frame engaging the front end of the truck, a loop at the juncture of the two sides, and a draft evener secured to the 02p- 7 in testimony whereof 1 hereto affix my signature in the presence of two Witnesses.
